IMPROVEMENT IN roTATo-DIGGERS'.

The Schedule referred to in these Letters Patent Aand making part of the` same.

To all whom it 'may concern.

Be it known that we, JOHN HALL, Jr., and OWEN FLANIG`AN both of Temperanceville, in the county of Alleghenyand State of Pennsylvania, have invented a new and useful Improvement in Potato-Diggers; and we vdo hereby declare that the following is a full,

clear, and exact description thereof, reference being vour invention, we will proceed todescribe'its construction and operation.

In the-accompanying drawings, which form part of our specification- Figure l is a side elevation of our improvement in potato-diggers. l

Figure 2 is a top. view or plan of the same.

.In the drawingsv A represents the beam, and- B the standard, to which the plow or digger O is attached, to tbe back or top edge of whichis pivoted, at m, a separator, consistingof a series of parallelrods attached to two cross-bars, n and o.

To theback of .the plow or digger is attached a piece, e, in'which is pivoted a wheel, f, the points of which strike against the cross-bar o of the separator,

and thereby causing itto rise and fall,'forl .the purpose` of impartiirga jarring action to the separator.

To the front end of the beam A is attached a hanger, l, to' which is pivoted the graduating wheel X, which may be raised Or lowered with relation to' 4the ground by adjusting the hanger l on the beam A,

andtbereby regulate the depth of the digging.

To the beam A are attached handles D, which are provided with braces R, for the. purpose of giving stii'- lness to the handles.

As the construction of our iurprovenientin potatodiggers will be readily understood from the foregoing description, and by reference to the accompanying drawings, we will therefore proceed to describe the operation, which is as follows:

' The plow or digger C enters the hill or row, and divides itylongitudinally, throwing the potatoes up, and the forward motion of thedigger will cause the potatoes topass back over the top edge of thedigger, onto -the separator, which will, by its jarring action, caused by the agitating wheel f, separate the loose earth vfrom the potatoes, which will, when thus separated, fall ofi' at the rear end of the separator Onto the ground, from which they can be gathered with ease and facility.

Having thus described the nature, construction, and operation of our improvement,

Whatwe' claim as of our invention is -The combination and arrangement of the plow or digger C, adjusting wheel X, separator and agitating wheel f, constructed, arranged, and operating with relation to each other as herenbefore described and for the purpose set forth. f j JOHN lHALL, JR.
